Comet Churyumov-Gerasimenko (or Comet CG in short) has a semi-major axis of 3.4630 AU, and an eccentricity of 0.641. (a) What is the closest distance of Comet CG to the Sun? This point in the orbit is called the perihelion point. (b) What is the largest distance of Comet CG to the Sun? This is the aphelion point of the orbit. (c) Make a sketch with the Sun, Mercury, Venus, Earth, Mars and Jupiter, and overlay on this sketch the orbit of Comet CG. The sketch should be to scale. (d) What is the orbital period of Comet CG? Use Kepler’s law for the Solar System. (e) What is the ratio of velocities at perihelion and aphelion, vp/va
